USB volume control wheel

thingiverse

Turn up... ... the volume. This simple project allows you to alter the system volume of your PC, Mac or even android phone. See it in action Inside are an Adafruit Trinked 5V microcontroller board and a cheap rotary encoder. All in all I spend less than 20€ on this project. Parts I used: Adafruit Trinket 5V, 8MHz 12mm rotary encoder 4mm M2 screw Micro USB cable Follow the instructions here to wire and program the electronics. Don't worry - it's really basic stuff. When everything is wired up, the controler acts as an usb input device wich sends out media key commands to your computer. Have fun printing | soldering | turning | listening | muting Post-Printing Wiring and board position exposed Alignment To align the two zylinders perfectly first slide the cap.stl onto the shaft of the rotary encoder. Next apply superglue to the base where the encoder will be placed in the next step. Now slide the zylinders into eachother and make sure that the gap between the parts is equal all arround. Once the glue dries you're done. Congratulations!
